So, you set the other two to be redundant -- i.e., put in the awaken
time twice and the retire time twice; or, awaken three times and
retire once; etc. This is a horrible kludge. And, when you later decide
to change the schedule (it's winter, have to get up earlier cuz there
are more activities going on!), you now have to replicate those
changes to these redundant settings.

Bottom line, think about how tech savvy you (and other occupants)
are and how easily you will adapt to IT'S requirements!

I once had one of these programmable stats. I found it to be a pain in
the ass to set it, and when the battery died, it had to be programmed
all over again. (Not an easy task).

I changed the furnace and the installer put on a new stat, one with no
programming. It only has one option, I can change the temperature, for a
one time use. Then it goes back to the prior setting. OR I can push the
HOLD button, which makes the change permanent.

He said this stat was MADE FOR my new furnace but I could put my
programmable one back after he left, if I wanted. I never put it back. I
would not buy another one. Of course, I should mention that I'm retired
and have no real schedule. When weather allows, I am outdoors a lot, but
the stat dont know when I'm not in the house. But if I go visiting, like
for Thanksgiving, I'll turn it down before I leave.

I never noticed that much savings in my gas bill when I had that
programmable stat. After all, if the temp lowers during the time you're
at work, the furnace has to run a lot longer to raise the temp again.

Just my opinion, but I think those programmable stats are over rated.
And if you dont live on a schedule, they are pretty useless.

NOTE: I only have heating, no cooling!
